SUSPENSION CONTROL SYSTEM 3G-5
GRAVITY SENSOR
Gravity sensor is installed in front of shift lever (selector lever for
A/T) and consists of weight, piezoelectric element, amplifier, filter.
As weight moves up and down in accordance with vertical move-
ment (vibration) of vehicle, that movement, after being converted
into electric signal by piezoelectric element, is transmitted through
amplifier and filter to suspension control module as voltage signal.
Receiving this signal, suspension control module detects the ve-
hicle vibration.
THROTTLE OPENING SIGNAL
Throttle opening signal is transmitted from TP sensor installed on
the throttle valve shaft to ECM as voltage signal. The signal is con-
verted to duty signal in ECM and it is sent to suspension control
module.
Receiving this signal, suspension control module detects the
throttle valve opening.
